This compound is widely utilized in bioconjugation and click chemistry applications due to its reactive tetrazine and azide groups. The tetrazine group enables rapid and selective reactions with strained alkenes or alkynes, making it valuable for labeling biomolecules in live cells or complex biological systems. Its PEG7 linker enhances solubility and reduces steric hindrance, improving efficiency in conjugation processes. The azide group allows for additional functionalization through copper-catalyzed azide-alkyne cycloaddition (CuAAC), expanding its versatility in creating complex molecular architectures. It is particularly useful in drug delivery systems, diagnostic imaging, and the development of targeted therapeutics, where precise and efficient conjugation is critical.
